[ale] Problem compiling program with MooTiff

[John M. Mills]

tt I am tryting to compile a program call Xmgr.  It requires Moo-tiff
tt which I have now.  It compiles fine, then gives the message:

tt   xmgr: can't resolve symbol 'XShapeQueryExtension'

tt Anyone with ideas as to what is wrong?  I can get another version of
tt the source and try to compile it..l

Not so fast.

I believe this is in the "X extensions" library package, which I have
as:
/usr/X11R6/lib/libXext.a   /usr/X11R6/lib/libXext.sa

Hope that gets you off the rock. 

Note that many such entries are listed in man3, for example:
*******
%man XShapeQueryExtension

XSHAPE(3X11)               X FUNCTIONS               XSHAPE(3X11)

NAME
       XShapeQueryExtension, XShapeQueryVersion, XShapeCombineRe-
       gion,     XShapeCombineRectangles,      XShapeCombineMask,
       XShapeCombineShape, XShapeOffsetShape, XShapeQueryExtents,
       XShapeSelectInput,  XShapeInputSelected,  XShapeGetRectan-
       gles - X nonrectangular shape functions

SYNTAX
       #include <X11/extensions/shape.h>
[...]
******

You can guess I dug this out, too.  When I installed MooTiff, I got a
boatload of man3 pages added to what I already had.  Very helpful.

If you generate a cascade of unresolved symbols, you might look at the
following makefile fragment for a static MooTiff build.  (I found for
that I also needed libSM and libICE.)

*******
SRCS            =       main.c
OBJS            =       $(SRCS:.c=.o)
PROGRAM         =       static_main
CC              =       gcc
DEPEND          =       $(CC) -MM
INCLUDE         =       -I/usr/X11R6/include
LIBDIR          =       -L/usr/X11R6/lib
LIBS            =       -lXm -lXt -lXext -lX11 -lSM -lICE
CFLAGS          =       -g -static $(INCLUDE)

all: $(PROGRAM)

$(PROGRAM): $(OBJS) 
        $(CC) $(CFLAGS) $(OBJS) $(LIBS) $(LIBDIR) -o $(PROGRAM)

clean:
        rm -f *.o *~ $(PROGRAM)
